thats poor imo - even worse that they decided to highlight the flaw by 'cutting out' a much bigger area than actually needed

Class 37 (884) at the rear of this Class 710 (103) and one at the front (601)!
Passed this formation at Colwich on the WCML yesterday, i presume heading to Crewe for testing.
Furthest North i had seen a Class 710, have there been others?
Maybe this is how they should run on the GOBLIN line!

Parrellel. The current software is suitable for the purposes of ECS movements.
Is this the first AC only unit that's been spotted out of Derby works?

Funny you should mention that because I spoke to a London Overground driver the other day and he told me that they weren't allowed to test them because of the software issues.
Several at Old Dalby.

Another 710 is out training today on the GOBLIN - just seen heading east at Harringay Green Lanes. Too far away to identify, I'm afraid.
It stopped there so presumably they are mimicking service/stopping patterns.

yes that is more than likely.
The runs yesterday and today were a trial of driver training with ASLEF reps / instructor ops on board. I saw two of them get off the train yesterday at Blackhorse Road. The 710 has been followed both days by a suitably equipped Class 37 rescue loco in case it failed. Both days of test runs appear to have gone OK in terms of the train running in the paths allocated with no demonstrable delays or issues if you look at Realtimetrains.
The line user group twitter feed reports that the WCML overnight testing is now allowed to use the fast lines and without a rescue loco in tow. There have been regular WCML runs for a number of consecutive nights which looks vaguely hopeful but without any detailed info as to units and mileage and any issues being found it's hard to be fully confident.
I assume that discussions will now take place between the relevant parties as to how and when driver training can commence for GOBLIN drivers. Beyond that there is still the hurdle of actually getting the trains signed off contractually and in terms of safety / assurance by ORR for passenger use. ORR must be very busy given how many different stocks are under test at the moment with, I assume, a progressive build up of technical and safety assurance paperwork being generated by multiple manufacturers for different train designs.

What on earth are they making up now? The WCML runs are using the fast lines because it’s two track overnight and this week the slows are closed. There is no “allowed” to use a different pair of lines for crying out loud! these havent been shadowed, the current 37611 use is purely to avoid performance impact of a sit down on the NLL.
OK don't shoot the messenger. Sorry if I've repeated nonsense - it was done in good faith.
There were two return class 710 driver training paths operated on Saturday 3/3/19 on the Barking - Gospel Oak route. As from Monday there are 4 return workings per day showing in Realtimetrains. These cover the late AM peak, late morning, mid afternoon and then early evening - all from Willesden Junction (bay platform 2) through to the Upney siding just east of Barking station.

I have a feeling that there will be some 710s in service just as the last 172s depart, there must be a lot of pressure on Bombardier from TfL at the moment.

Don't you mean Saturday 2/3/19.

The 302s, 305s & 308s could do the 6.25 / 25 kV ac but the 307s couldn't so were restricted to the Southend Vic service

Upney siding?
AFAIK, the only sidings at Upney are between the up & down TfL District line tracks.
I think it must be possible to reverse from platform 7 to 8 via the connection from the up Southend line, the junction is quite a distance from Barking station & possibly with bi-directional signalling. It's certainly long enough for a 4-car unit to be held whilst changing ends.

That sounds right, the location actually listed in RTT for tomorrow’s runs is “Barking Upney Junction” rather than sidings as posted earlier...
Sorry, lack of precision on my part. It is "Barking Upney Junction" as cited by SWT Passenger. One day I will learn to be 1,000% precise when posting to transport groups. I never learn.

Seems a very odd design choice, though a similar issue afflicts the Siemens 700 and 707s so it’s not just Bombardier
I don't believe that is correct, the 307s lasted until 1993, and the GE lines had been progressively converted from 6.25 to 25 Kv before that.

No worries! Precision it not required........
I've lived in LT&S land since '75 & I was wondering if there was a new siding on the Tilbury line.
It used to be 4-tracked as far as Ripple Lane yard but the down line junction for the yard was moved away from Barking, so there would be space for a new siding, but the satellite view showed otherwise.......

Maybe none of the NE London lines depots signed 307's? I've never seen a 307 coupled to any of the other Mk1 EMU's, they certainly didn't have the same control systems. (They still used the original DC resistance controls rather than transformer tap-changing & a rectifier to vary the voltage to the DC traction motors.)
That's due to come back, so these 710s can get to Barking Riverside.

Good point Sir. Do we know where the Riverside junction will be located, before or after the A13 bridge?

They certainly used to be used on the NE lines to bishops stortford. Also they regularly joined up with 302 305 308. Example here https://flic.kr/p/effVZq

After Renwick Road overbridge, according to the non technical summary presented for the TWA. Running line usage is altered almost all the way back to Barking though.
This has previously been discussed in the Barking Riverside thread in the infrastructure forum though.

Think we can only be a bit more patient from this point on wards as the 710s seem to finally have a functioning software (fingers cross) and they can build up enough mileage without another breakdown.
As for the 172s departing before the 710s start that was pretty obvious from the start the way Bombardier been conducting their software. It's just a shame TFL didn't take the user group's advice sooner in deploying some 378s. Personally if it were me I would pull one more from NLL, WDCL, & ELL each to make a proper six unit service. Doesn't matter if other services suffer from some delays in the meantime (5% loss!) it's only a temporary measure till the new trains come into service.
Anyways I hear theres some more runs and testings with the 710s on the Goblin, is this just for driver familiarization training and WCML is being used for mileage accumulation or a combo of both purposes just to cut in some time?
